In April 2026, the Rails team completed a focused modernization of time handling to ensure Ruby 3.x compatibility. This work removed an outdated time-handling code path that was only relevant for Ruby versions prior to 3.3.1, simplifying maintenance, reducing technical debt, and improving code clarity. The change is linked to a single, well-documented commit that explicitly notes the minimum Ruby requirement (3.3.1) and provides traceability for future upgrades. This sets Rails up for smoother Ruby upgrades and reduces risk when upgrading Ruby in production environments.
